Question

Consider the file score below, which provides the scores of each student in five different assessments.

$ cat score

pchen72 50 71 55 93 115

jmaszk   45 76 49 88 102

bvbui    59 78 53 96 145

mtcrowle 33 65 39 82 100

mrchave3 54 77 56 98 158

Write a python script that computes the final percentage score for each student, as well as the class average

The max score is 450 and must be set as constant.

The output should be (round the score to nearest integer):

Total number of records: 5

Final score for pchen72 = 85%

Final score for jmaszk = 80%

…

Class Average = 86%

The header line should show: Final Score computation

Explanation / Answer

data = []

with open('score.txt') as f:
   for line in f:
       split_line = [i for i in line.split() ]
       data.append(split_line)

length = len(data)
class_percentage = 0
print " Final Score computation "
print "Total number of records:",length

for student in data:
   score = student[1:]       #take out all the score part
   score = map(int, score)   #to convert string into int
   percentage = (sum(score)*100.0/450.0)
   class_percentage += percentage
   print "Final score for ",student[0]," = %.0f"%percentage,"%"

class_percentage /= length
print "Class Average = %.0f"%class_percentage,"% "
